-- An Oklahoma woman believes outrage over the Florida murder case almost cost her her life. The 26-year-old says a crazed woman tried to kill her because the woman thought she was Casey Anthony.

It happened in Chouteau last Friday night, July 8, 2011, just days after the Casey Anthony verdict.

Sammay Blackwell hopes she never hears this again:

"You look like Casey Anthony, I'm like 'okay,'" she said.

Blackwell doesn't think it's funny after what happened last week.

Blackwell works at a convenience store in Chouteau and said Shireen Nalley came in that night around 10 p.m. and looked strange, very suspicious, then left after buying gas.

"I just couldn't keep my eyes off of her," she said.

Sammay got off work at 10:30 that night and walked out to her car, which was parked on the other side of the building, and got inside.

"Began to back out and looked and I could tell she was staring directly at me; I could almost see the whites of her eyes," she recalled.

"I proceeded to pull out of the parking lot, and she was right behind me," Sammay said.

Blackwell drove a few miles and says Nalley suddenly rammed her van into the back of Blackwell's truck.

"I said, 'Oh my God, help me,'" Blackwell told News On 6.

She then pulled into a parking lot to get away.

"She hit me again, causing my vehicle to flip two and a half times, landing on the driver's side, and I just laid there playing dead," she said.

Blackwell's mother says she'll never forget her daughter's reaction.

"I got to her, she was crying, she was shaking, she says, 'Mama, this lady thinks I'm Casey Anthony and she tried to kill me," her mother said.

Police chased Nalley for a while and finally arrested her for assault and battery with a deadly weapon. Nalley told police she was "trying to save the children."

"She said that I was trying to hurt babies, I was killing babies and she was going to stop it before it happened again," Blackwell recalled. "She could have taken me away from my family, my daughter."

Blackwell's daughter is also named Caylee -- the only thing Sammay said she has in common with Casey Anthony.

"I don't look that much like her, so what about people who actually do look like her and live closer to Florida, instead of Oklahoma, what's going to happen to those people?" she said.

Nalley is in the Mayes County Jail on complaints of assault and battery with a deadly weapon, leaving the scene of a vehicle collision, resisting arrest and reckless driving. She is being held on a $25,000 bond.

Police say Nalley seemed to be on drugs when they arrested her.

Sammay Blackwell wants to get a restraining order against Nalley. Blackwell also says she's struggling with Nalley's car insurance right now and claims the company won't cover the damage if Nalley hit her on purpose.
